Abstract
This invention provides an element for displaying one or more portions of characters or shapes, wherein the display element comprises partially transparent plastic in which fluorescent colorant is incorporated. Preferably the inside of one head end is provided with a profiled form.
Description
WO 92/06461 PCT/NL90/00146 1 DISPLAY ELEMENT OF TRANSPARENT PLASTIC WITH FLUORESCENT COLO-
RANT
The present invention provides a display element accord-' ing to claim 1.
Such a display element shows for instance text in very clear manner if a number of these display elements are arranged in a background, for example a metal grid provided with holes, and if light or (partially) invisible radiation such as so-called "black light" falls onto such a pattern of display elements.
In preference the inside of the head end of a display element takes a profiled form so that a rear side of the display element results that is provided with facets, whereby the front view of the display element exhibits, a highlighting illup,ination.
A most preferred embodiment of such a display element is provided with concentric rings at the head end of the inside thereof; when radiated such a display element is the most clearly noticeable relative to a plurality of different display elements which were injection moulded by way of experiment with differing profiling on the inside of the head end.
Further advantages, features and details will be elucidated in the following description of preferred embodiments of the present invention with reference to a drawing, wherein: fig. 1 shows a perspective view of a background provided with a first embodiment of the present invention; fig. 2 is an oblique front view of a display element of fig. 1; fig. 3 is a partly broken away, oblique rear view of the display element of fig. 2; SUBSTITUTE SHEE T WO 92/06461 PCT/NL90/00146 2 fig. 4 shows a partly broken away, oblique rear view of a second embodiment of the present invention; and fig. 5 is a perspective, oblique front view of the embodiment of fig. 4.
If in a background 1 (fig. for instance a metal grid, display elements 2 are arranged in a particular pattern, texts or shapes can be shown'as desired herewith in the grid 1. The display elements 2 are manufactured from transparent plastic with fluorescent colorants such as for instance those made commercially available by the Bayer company under the name Lisa. A particular illuminating effect results when such display elements 2 are radiated with light (sunlight (also diffuse), artificial light) or ultraviolet radiation such as "black light". The colorants relate preferably but not exclusively to fashion colours such as turquoise, violet and the like. The radiation generated in the display element by fluorescence will exit substantially via the convex head end, A display element according to the present invention also displays a conspicuous appearance if radiated from the jacket end 1 from behind the grid, for instance by means of a black light.
A display element 2 preferably has roughly the form of an internally hollow toadstool provided with an approximately rounded conical or convex head end that projects over a hollow cylindrical end 4 so that the head end 3 has a large target surface ftr the radiation. The radiation enters via the head end into the interior of the transparent display element.
The cylindrical jacket 4 is preferably provided with a snap-in edge 6 for snapping-in that jacket end into the grid 1. The display element 2 (fig. 3) is in preference provided on the inside of the head end 3 with concentric, annular edges 7, 8 and 9 which are staggered respectively in lengthwise direction of the display element 2 and which form facets for reflection of the radiation entering the head end which, as with a diamond, cause a shining/sparkling, with the result SUBSTITUTE SHEET WO 92/06461 PCT/NL90/00146 3 that the display element is very highly visible.
Another embodiment 12 of the display element according to the present invention (fig. 4, 5) is provided with a convex head end 13 and a plurality of comparatively small facets 14 which are arranged in an inner wall 16 which runs parallel to the head end surface 13.
The embodiment shown can be manufactured in elegant manner in large quantities with a device for injection moulding of plastic.
SUBSTITUTE SHEET
Claims (5)
1. Display element for displaying one oir more portions of characters or shapes, wherein the display element comprises partially transparent plastic in which fluorescent colorant is incorporated, said! element including: a cylindrical end for insertion into an opening of a background; and means for snapping the display element fixedly into the opening.
2. Display element as claimed in claim 1, provided with an approximately convex head end having a diameter greater than the outer diameter of the cylindrical outer end.
3. Display element as claimed in any one of the claims 1 or 2, provided with a head end of which the inner wall o *facing toward the cylindrical end takes a textured form.
S4. Display element as claimed in claim 3, wherein the inside of the head end is provided with concentric, annular edges or reflection surfaces located at mutual 20 intervals in lengthwise direction of the display element.
5. Display element as claimed in any of the foregoing claims that is manufactured according to an injection moulding technique.
